Polar Heart Rate Monitor

scrappy11

I have one of these and it seems like when I walk its okay and it shows my correct heart rate and than when I run my heart rate sky rockets and I know for a fact that isn't true. I am pretty well-endowed and I am wondering if this is why. I have been running for quite some time now and this hasn't been happening until recently. I am really confused, and want to know if this has happened to anyone else.
Thanks.

I have had that issue once or twice. Could it be time to change your battery? Or, you might need to tighten the strap. I feel like the strap needs to be making a mark to accurately get my heart rate. Good luck!

I believe you are supposed to wear the monitor just below your breasts, so even if they're large they shouldn't be causing the problem. As the previous poster said, I'd just double-check that the unit is making proper contact. You can use a gel to help with conductivity.
